Hi Noob!
How old are you?
This would be a great first session for a rank novice. Which is great, because that's what you are. I'd highly suggest you get verified and request a form check on squats from the Starting Strength Coaches board. You can find information on both by going to the stickys on that board.
If you can swing a visit to a coach in person or afford to hire Starting Strength Online Coaching, do so.
Don't let anyone insult you. Don't compare your lifts - especially your first day - to anyone else. Where you start doesn't matter very much, and neither does where you end on LP in terms of a lifting career. Just be sure to add reasonable amount of weight each time to each lift.
On the nutritional side of things, use the search function in the nutrition forum run by Santana. You may not find the exact situation you're in replicated (likely not), but you will get the guidance you're looking for. You seem to be off to a good start on nutrition: 1g of protein per lb bodyweight is a good stock recommendation.
On your bench press for this session you made jumps that were too big. The good news is that you are likely able to get 100x5x3 on your next time benching, simply because you are so unaccustomed to training. When you do your first press workout, you may try 10 pound jumps from the bar, i.e. 45-55-65, maybe 75.
Without video, it will be difficult for anyone to tell you how much you should go up in load next time on squat and deadlift.
Last bit that I can see already: I'd highly suggest doing multiple sets with the empty bar. The extra reps help warm you up and give you additional practice. 2-4 sets with the empty bar is the norm.
